Question

I have no idea how to do this one please help

Answer 1

a = -14

Explanation:

We are given

`(2a+38)/(5) = 2\\`

We want to get the variable by itself. First, we can multiply both sides by 5 to get rid of the fraction

`((2a+38)(5))/(5) = (2)(5)\\2a + 38 = 10`

Now we can isolate the variable by subtracting 38 from both sides

`2a + 38 - 38 = 10 - 38\\2a = -28\\a = (-28)/(2)\\a = -14`
